"FAA Expands Boeing Investigation to Subcontractor"

The FAA has expanded its probe into Boeing's manufacturing practices and production lines, focusing on subcontractor Spirit AeroSystems, following an incident where a door plug fell off a Boeing 737 Max 9 midair. This led to the grounding of all 171 Boeing 737 Max 9 airplanes in the US. Alaska Airlines, which has 65 of these planes, is experiencing significant flight cancellations. The FAA is prioritizing safety over speed in returning these aircraft to service, and the NTSB is investigating the incident.
